SANDY Easdale has quit Ibrox as the new board launched a probe into the bus tycoon and two other directors.

The Greenock-based businessman was suspended, along with Derek Llambias and Barry Leach, and the trio were ordered to halt their duties on the football board.

Castlemilk-born businessman Dave King took charge of the club last week.

It was announced last night that Easdale would be following his brother James out of the Ibrox door by quitting with immediate effect.

The current board revealed his resignation and said the club would not proceed with their investigation.

In a statement, the club said: "Mr Easdale has agreed to resign from his directorships with the Group with immediate effect.

"And he does so wishing the club, its supporters and the new Board every success for the future.

"The club thanks Mr Easdale for his co-operation in this changeover and confirms the investigation previously referred to will not now proceed.

"The club is also happy to confirm that Mr Easdale did not receive any remuneration in respect of the directorships he held with the club."

Meanwhile, a newly-appointed Rangers board member is at the centre of controversy over a sexually explicit cartoon of the prophet Mohammed.

The club is looking into a tweet from the account of Chris Graham sent by way of reply to radical Islamist preacher Anjem Choudary on the day of the Charlie Hebdo attack.

Graham was appointed as a non-executive director at Ibrox on Tuesday after King swept to power with a staggering 85 per cent of the EGM vote.

On January 7, shortly after two gunmen had shot dead 12 people at the offices of the French satirical magazine in Paris, the preacher posted a message on Twitter which read "freedom of expression does not extend to insulting the prophets of Allah, whatever your views on the events in Paris today!"

A tweet from Graham's account responded by posting a cartoon depicting the prophet Mohammed engaged in an explicit sexual act.

Part of the message accompanying the drawing read: "You probably won't like this one... then."

The 38-year-old is well known among football fans for representing the Rangers Supporters Trust. His Twitter account is offline.
